Did you get it sorted? I can try to explain...there are 4 pieces (dogbone shaped piece, saddle clamp with a rubber center link, and 2 halves of the clamp) I think and 3 screws. The 'dogbone' shaped piece goes in the seat post slot. The piece that has the rubber center goes on top of the seat post rail, and the two shorter allen head screws screw into the dogbone shaped piece. The other two pieces fit around the saddle rails and the saddle clamp with the rubber center. Does that make sense? We tighten our saddle clamp from the drive side. When ours shipped, it shipped complete with two 'dummy rails' in the saddle clamp. Obviously take those out.
